| 摘 要： | 用６个抗青枯病花生品种，分析了株高、总分枝数、总果数、饱果数、百果重、百仁重、出仁率、荚果产量等８个性状的遗传变异系数和遗传力，各性状对产量的遗传相关系数和相关选择效果。多数性状的遗传变异较小，选择效果不大．各性状的单株遗传力普遍低，群体遗传力则相对较高。因此，以高产为目标的抗病育种应以集团选择为主。

| Abstract: | Six groundnut cultivars resistant to bacterial wilt were uest to study the genetic parameters of eisht agronomic/economic traits. All the eight traits had senerally low coefficients of genetic variation with relatively poor selection effects. For all the traits observed,the heritabilities estimated based on the data from individual plants were lower than those based on population observations. Thus a bulk selection method might be more desirable for high yield potential in breeding. |
